Suppose that energy is used at a rate proportional to the mass to the 3/4 power (as in Example 1.7.24). In this case,

Find the units of a2 if V is measured in cm3 and t is measured in days (they should look rather strange). Find the equilibrium. What happens to the equilibrium as a1 becomes smaller? Does this make sense? What happens to the equilibrium as a2 becomes smaller? Does this make sense?
Small organisms like bacteria take in food at rates proportional to their surface area but use energy at higher rates.
